PLASTERrBOARD SUPPORT.

Specification of Letters IPatent.

Patented Dec. 18, 1917.

Application filed May 10, 1916. Serial No. 96,517.

Board Supports, of which the following is a specification.

This invention relates to improvements in walls and ceilings whereinplaster boards, pulp boards, fiber boards, and the like are used as aground for the plaster, and has to do particularly with the means ofsupporting the plaster boards in place.

Plaster boards come in rectangular sheets of uniform size. The sizescommonly used range from eighteen to twenty-four inches Wide by fromtwenty-four to thirty-six inches long. They are commonly supported fromsmall channels or I-beams about an inch or more in depth andthree-eighths or one-half an inch in flange width, and as the alinementof these supporting members cannot be exact, and as the spaces betweenthe edges of the plaster boards may vary from one-quarter to one-half ofan inch, it is not practlcal to attempt to make the edges of the plasterboards register exactly with the flanges of the supporting members.

The objects of the invention are to take care of misalinement of thesupporting members and plaster boards by the use of flexible ties andsupports for holding up the edges of the plaster boards, and to arrangethe supports and ties for securing the plaster boards to the supportingmembers so that the plaster boards can be placed and secured by one manwithout any helper. A further object of the invention is to support theplaster boards snugly against a r gid back- 1ng so as to permitplastering their exposed surfaces.

The invention consists in arranging wires or other suitable spacersbetween the plaster boards and the channel or I-beam supporting members,and in holding the plaster boards snugly against the wires by means offlexible metallic ties, such as wire loops, passing around thesupporting members and between the edges of adjacent boards and twistedat their exposed ends around plates which span the spaces between theboards and'support their edges.

Further objects of the invention appear in connection with thedescription of the plaster board ceiling shown in the accompanyingdrawings, and in the process of erection thereof, hereinafter described;and what the invention consists in is more par ticularly set forth inthe appended claims.

In the drawings, wherein the same reference characters designate likeparts in the.

several views,

Figure 1 is a perspective view of the under side of a ceiling embodyingthe invention, prior to completion, showing part of the plaster boardsin place;

Fig. 2 is a cross-section of a small por tion of the ceiling, showing asupporting member and the edge portions of two adj acent plaster boards;

Fig. 3 is a perspective view of a tie plate;

Fig. 4 is a perspective view of a special form of tie plate forsupporting the edge of one plaster board only; and

Fig. 5 is a perspective view of a supporting hook for supportingtemporarily one edge of a plaster board during erection.

Figs. 2, 3, 4 and 5 are drawn to the same scale, which is larger thanthat of Fig. 1.

In the construction shown in the drawings, wires 10 are strung acrossthe under sides of the supporting channels 11 from ter boards and arelooped around the supporting channels 11. Each of the plates 13 has apair of holes 15 through it at its middle on opposite sides of themedian line, and slots run into these holes from the opposite edgesofthe plate, as shown in Fig. 3. This arrangement permits the wires 14to be passed through the holes 15 without difliculty, and insures thatthe plates shall not sli out of place after having been tied up.

The plaster boards. are erected one at a time, and are held in place atone edge temporarily by clips 16 which hook over the supporting membersand have their lower ends bent horizontally to form supports l7 forslipping under the edges of the plaster boards. The opposite edge ofeach plaster board is supported by the workman while the permanent ties14 and plates 13 are being placed under it. Prior to tying up the nextrow of plaster boards, the clips 16 are removed and are replaced byangle-shape plates 18, which have slotted holes 19 for tie wires, andare secured to the supporting members like the plates 13. The legportion of each angle clip 18 rests against the lower flange of thesupporting member, and the edge of the adjacent plaster board is setagainst it to space the boards at a suitable distance apart, as shown inFig. 1. This manner of erecting and securing the plaster boards enablesa row of them to be placed by a single workman with no trouble, andincreases the speed with which a ceiling can be erected as all theworkmen can work independently.

The wires 10 provide a continuous backing for laying the plaster boardsagainst and alining them, and also space the plaster boards away fromthe supporting members and enable the tie wires to be looped around themwithout difficulty. The wires 10 are arranged well within the margins ofthe plaster boards, and are still enough to hold the plaster boardslevel for plastering.

What I claim as my invention and desire to secure by Letters Patent is:

1. In a plaster board construction comprising supporting members, Wiresstretched transversely of said supporting members, plaster boards laidagainst said wires with their edges in alinement with said supportingmembers, said wires spacing said plaster boards away from saidsupporting members, and means for supporting said plaster boards againstsaid wires.

means? 2. In a plaster board construction comprising supporting members,wires stretched transversely oi? said supporting members, plaster boardslaid against said wires with their edges in alinement with said supporting members, said wires spacing said plaster boards away from saidsupporting members, and means for supporting said plaster boards againstsaid wires, said means being arranged in the spaces between the edges ofthe plaster boards and the supporting members.

3. In a plaster board construction comprising supporting members, wiresstretched transversely of said supporting members, plaster boards laidagainst said wires with their edges in alinement with said supportingmembers, said wires spacing said plaster boards away from saidsupporting members, and flexible means attached to said supportingmembers for supporting said plaster boards against said wires.

4. In a plaster board construction comprising supporting members,plaster boards laid with their edges in alinement with said supportingmembers, continuous means between said supporting members for spacingsaid plaster boards away from said supporting members, wire loopsengaging said supporting members and passing between the edges of saidplaster boards, and metal plates arranged against the edges of saidplaster boards, said wire loops engaging around said plates for holdingthem in place.
